Answer:

First subtract the number of students who take both subjects from the number of students who take Consumer Education

22-4=18

Then,

subtract the number of students who take both subjects from the number of students who take French

20-4=16

Now,

Add 18,16 and 4 and subtract the sum from the total number of students in the class

=80-(18+16+4)

=80-38

=42

The perimeters of the square and the triangle shown below are equal. What is the value of x?
Rudiy27
Perimeter is the sum of all the sides. So we can set up an equation:

\sf 3x+1+3x+1+3x+1+3x+1=2x+8+x+8+4x+2

Now solve for 'x', combine like terms:

When it comes to terms with variables it's just like normal addition but we keep the variable:

\sf 3x+3x+3x+3x=12x
\sf 2x+x+4x=7x

So we have:

\sf 12x+1+1+1+1=7x+8+8+2

Add:

\sf 12x+4=7x+18

Subtract 7x to both sides:

\sf 5x+4=18

Subtract 4 to both sides:

\sf 5x=14

Divide 5 to both sides:

\boxed{\sf x=2.8}

mylen [45]

Answer:

up to $338.18

Step-by-step explanation:

Use the compound amount formula:

A = P(1 + r/n)^(n*t), where r is the interest rate as a decimal fraction and n is the number of compounding periods per year.

Here, A = $300(1 + 0.04/12)^(12*3), or

          A = $300(1.0033333)^*36, or

          A = $300(1.127) = $338.18

Nina will be able to spend up to $338.18 on a new bike.

Sergeeva-Olga [200]

Answer:

  x ≈ 0.7798

Step-by-step explanation:

For this to be an exponential function, the variable needs to be in the exponent. That is, parentheses are needed.

  e^(8x) = 512

  8x = ln(512) . . . . . take the natural log

  x = ln(512)/8 ≈ 0.7798
